lla it known that I, (lin-iam# lmsiz, n

citizen of thv United States, iwi-lin ut` Saloni, in tho county of Essex und m inonwcalth of .\lus-'a liu.-ctts, havo invented curtain lniprovunients in liurnishing-L'Iuchinos, of whit-h the following description, in roniu'otion with the aouonipanying drawings, is a specification. like refcniice chara ti-r.- on thu dra wings indicating like parts in the sew-ral ligurrs.

Thixl invention relatos to machines for linis'hing loatlirr and purticularl to ma chinos :ula itt-il for use in linisliin" the surfarvs of tir hrrls :unl solo of lioots and shops.

'l`hc ohjot of thc invention is particularly to improv(- tlio conatrurtioiil of the huruishing or other finishing tools used in machines of this class and to provide an improved rest having capacity for adjustuil-nt to ciiahhe heels varying in shape to lio .properly snppoited thereby iii position' to be artcd upon hv tlu saine tool.

.\n inmorlant feature of thc invention conuists in a hurnishin r or other finishing. tool, comprising a rarricr and a plurality l-f work members forming the working facc of thil tool. in which tlil work members un. yieldingly mounted und artI normally held in positio'n to form a rvgular or uniformworking l'uve for tlic'too iidtii'itliatiinin variations or lark of uniformity in tlioyiel ing Supporting moan.

l'n tho embodiment of the invention herein illustrati-d tlio work members, which are ahown as having rvlatcly long acting faces t-xtonding ari-os tho working face of thc lutrni-hing tool and collectively fortuin --iuh working favo, arcl pivotnlly connecte( to loaf spring-h which tcud normally to tluuoil.' uwmln'rn are provided with mctm coat-ting willi lixml int-ans on tho carrier for limiting tlu- |\'tint to whirh tlnl work mtimlu-r.- aro pressi-l outwardly liy the. springs and :it-o for determining thv angular posilinli of lliov il'l\' liullllit'l'` t't'li|ll\'('l t0 tlltfll |i\ot.-. rr ayonrutrly .shaping aid two oo- :u'ting liu-ana tluwork Inonilu-rh will lit! litltl n regular'or uniform working face irrespective of variations in the shape or strength of the springs, due, for example, to warning or twisting 'of the springs, uneven tt uipering, or changes in the shape of the springs during uae'.

A nother very important feature of the invczition is that, in the construction herein shown. the work members aro supported so that they may rock or tip with relationto their sustaining means, whereby the working face of thc tool may coliform to the sui*- facc of the work presented to it, as, for instance, if the contour of the work is ditlerent from that ofthe workin face; and also, if the work is so present as to engage ai one edge of the working face, the w members may tip and, aa rein shown, also yield, so as to conform to the ition as well aa the contour of the work and therefore engage the work with the entire width of the workin face of the tool.

The invention is herein shown as embodiedjin a machine comprising a rotary burnialiing tool having the working fam on the circumference of the tool; but the invention is obviously not limited to this form of tool, and sonic features of the invention also nia be employed to adv-intage in tools intended for other purposes than burnishing and ana u, una. D

Still another feature of the invention il an im roved work neat adapted to be ao adjust as to assist the operator in properl presenti the work tothe bumishin too Other eaturca of the invention inc udmg certain details o! construction an combinations of parts, will bc hereinafter described and pointed out in tlio claims.

The invention is herein shown as embodied in a machine adapted for burnishing or finishin the edges of heeis of boots and shoes. he machine comprises a frame l, a portion only of, which is shown in Fi 1 und 2, the frame having bearings 2 or7 a sliuft`4 upon which the burnishiii v tool is secured for rotation therewith. 'ihe burnishingtool is shown as com rising a carrier hereinafter more fu ly described, said carrier being in the form of a sleev adapted to tit on a reduced portion 6 o1 the shaft 4. The reduced portion of the shaft is provided between its ends with slots 8, which, as shown, do not extend to the end of the shaft, and with a ntral, longitudinal bore comprising a screw-threaded portion 10 and a smooth rtion 12 of less diameter than the threa ed portion. A bolt having a screwthreaded portion 14 and a tapering end portion 16 is adapted to be, screwed into the bore, its tapered portion 16 engagin the shoulder formed at the outer end o the portion 12, and thereby ,expanding the slotted rtion of the shaftto cause it to engage he carrier 5 frictionall for firmly securing and accurately centering the burnishin tool on the shaft. B locating the, slots 8 tween points within t e ends of the shaft as shown the enlargement of the shaft produced by the expandingalevice is greatest approximately midway tween the ends of'the ,slotted portion of the shaft, instead' of at its end, as would be the case id the slots extend ,to the end of the sha By reason of the present construction the teol is more accumtely centered and more firmly held in position than would be the case if the ex ansion of the shaft were greatest at the ens of the shaft.

The burnisliing tool here shown as ein: bodyiiig the invention com rises, besides the carrier 5 above mentions a plurality! of worlr members 20 which are mounted on the carrier for rotation therewith. The work members are so connected to the carrier as to be capable of 'movement inwardly 'and outwardly relative to the carrier and also to have other movements iis will be described. .Thepovlvtoi: memlersf are heroin s own as sup upon ea sprin 22, ailthough of course they might be yielisn fly supported by other means if desired. lit i these' ends in viewv the carrier' is formed with a portion 24 of relatively large diameter, a reduced rtion 26, and a flan ed outer end 28. e portion 24 is provi ed 'th longitudinal ves 30 separated by ribs 32, see Fig. 8, t e grooves forming seats in which the rear portions of the springs 22 fit snugly, while the rils hold the s rin securely a inst lateral movement, at is movement in the direction of the width of the springs. Clamping bolts 34 extending.

througllli the springs and into the carrier bind e springs tirmly in place within the grooves 30.

In accordance with the present invention the work members are movably mounted on the springs 22 and to this end the sprin are each provided iieai their free, front en with outstanding ears 40, which, as here'ii shown, are formed on a clip 42 secured to the s ring. Between the ears 40 is arran the oot 44 of a work member 20, which, as

shown, is connected to the ears by means of a pivot pin 46. The work members may, lhoweverz be mounted on the springs in any other suitable manner which will permit of a rocking or tipping movement of the work members.

The angular position of the work members with relation to the pivots 46, or with rela tion to the springs 22, is determined by providing the feet 44 of the work members with forwardly and backwailiv extending lugs 48, 49 w ich are ,iirran for en l'agement witli positioning means sup rt y the carrier. As shown, a sleeve is arra outside the carrier and is secured thereto by screws 53 which pass'tlirou h a flange 52 of the sleeve inte 'the rear end thus be seen that said sleeve and lip form positioning means which by en ment with the work members determines t e noriniil position of said members, and by insuring a uniform normal position for the several work members insures a liar and even workin face for the tool. t will also be unders that the springs serve to hold the work `nieiiibers yieldiiigly outwardly .ii ainst said positioninineans, but permit tie work members to forced inwardl' toward the carrier by, pressure of the wor of the carrier ,as illustrated in Fig. 2. The front end of the end 28 of the carlll against the working face of the tool; The u movable connection .formed by thol iivot 46 between each work member and its supporting spring also permits each work member to rock' or tip against the pres sure of the s ring, as shown on the lower side of ig. 5, while the elasticity of the spring enables each work niember to tip-slghtly in n direction at right angles to the irection of its movement about the pivot 46. This capacity of the work ti and having specifically described a conction the several features thereof in a pre erred form, I claim as new and desire to secure by Letters Patent in the United States 1.
